SPECIFICATION forming part of Letters Patent No. 532,417, dated January 8, 1895. Application filed September 19, 1893:. Serial No. 485,811. (No model.)

To aZlw hom it may concern:

Be it known that I, HENRY R. CORKHILL, Jr.', of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Multicolor-Print.- ing Presses; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference numerals marked thereon.

My present invention has for its object to provide a machine adapted to print upon a web of paper, pasteboard, or similar material, from several forms, and preferably in different colors, which web may be afterward severed into sections orpieces, preferablyadapted for making'knock-down boxes or cartons, though capable of being used for other purposes, and to these and other ends, it consists in certain improvements in construction and combinations of parts, all as will be hereinafter fully described and the novel features pointed out particularly in the claims at the end of this specification.

In the accompanying drawings:Figure 1 is a side elevation of a machine or press constructed in accordance with my invention; Fig. 2, a view of the opposite side; Fig. :3, a detail of the supplyroll and brake; Fig. 4, a longitudinal sectional view ofthe machine;- Fig. 5, a cross-sectional view; Fig. 6, an enlarged side elevation of one of the inking devices; Fig. 7, a section on the line yy of Fig. 8; Fig. 8, adetail view of one of the inking rollers and its bearing, the devices for adjusting the latterbeing shown in sections; Fig, 9, a sectional view on the line zz of Fig. 7; Fig. 9 a sectional view on the line a-b of Fig. 1; Fig. 10, a section on the line cd of Fig. 9; Fig. 11, a cross-sectional view of one of the impression cylinders carrying the printing form; Fig. 12, a longitudinal sectionalview of one end of the same; Fig. 13, a perspective View of one of the printing form cylinders showing the adjusting devices for the form; Fig. 14, a sectional view on the line e-f of Fig. 5; 'Fig. 15, a sectional view on the line g-h of Fig. 1. I V

Similar reference numerals in the several figures indicate similar parts.

The main frame of the machine is composed offside pieces 1, 1, connected by suitable tie rods or bolts 2, and resting upon and secured to a base frame or casting 3.

4 indicates a cross-shaft supported in suit able bearings 5 in the main frame carrying the main cylinder or cylindrical platen 6 arranged between the sides of the frame. Upon the Outer end of the shaft 4 is arranged a large gear wheel 7, and meshing with this gearwheel is a gear. 8 on a shaft 9, "which latter is also provided with a belt pulley 10 and flywheel 11 and actuated from a suitable prime mover.

13 indicates a frame mounted upon the base frame 3 at one end of the machine having upon its upper end a shaft 14, upon which the roll 15 of paper or cardboard to be printed is mounted; the web 16 of said paper extending under a suitable guide pulley or roller 17,-0ver a small scraper 18 and another guide pulley 19, thence around the cylinder or platen 6,

1 (around the periphery of which the cylinders carryingthe printing forms are disposed.) and through suitable tension and severing devices, as will be presently described.

Upon the end of the shaft 14, carrying the roll of paper, is a suitable pulley ordrum 2O having a groove in its periphery receiving one 'end'of an arm 21, through which passes a threaded shaft 22 having'a handle 23, and by operating the latter the shaft 14 and roll of paper may be moved back and forthin its bearings in the frame l3'to provide for the endwise adjustment of the roll and properly position the web on the cylinder 6. 'I helower end of the arm 21 operates in aflongit udinal groove in a stud 24 and is thereby steadied, and pivoted upon the stud 24 is a lever 25 suitably weighted and connected to a brake strap 26 passing over pulley 20 and secured to the frame 13, as shown in Figs. 2 and 3,

thereby giving the necessary tension to the are all similar, a description of one of them will suffice.

For convenience of description, I will term the cylinders, on which the forms from which it is desirable to print, type cylinders, though, as farther on explained, the forms are preferably etched zinc plates, and each contain the part of the complete matter that is to be printed in a single color.

Each of the type cylinders is mounted upon a shaft 27 adjustably supported in bearings 28 in the main frame, which bearings are capable of vertical adjustment by means of adjusting screws, as shown, and upon the outer end of said shaft is a disk 29 to which is connected a gear 30, by means of bolts 31 operating in suitable slots in the gear and permitting a slight rotary movement to provide for the rotary adjustment of the type form independently of the cylinder 6, and of the other type cylinders. The shaft is further provided with a collar 32 in one end, and at the opposite end with a nut 33 for clamping the cylindersecurely to it, and set nuts 34 are arranged on the shaft next the bearings 28 by means of which the longitudinal adjustments of the cylinders can be accomplished, as will be understood.

The printing or type cylinders are com posed of a central core piece 35 encircling the shaft 27 and provided with two or more circumferential undercut grooves 36 and with a longitudinal dovetailed groove 37, and arranged over this core are preferably two semicircular sections 38, held in position by screws 39 engaging blocks 40 fitting the grooves 36, and

capable of a slight rotary motion on the core 35. The proximate sides of said sections 38 are arranged at an angle with each other be tween which operates a sliding wedge or key 41, its outer periphery being flush with the sections 38, while its inner side is, provided with a dovetail projection fitting the groove 37 in the core 35. A gear 42 is arranged between the collar 32 on the shaft and the cylinder, through which operates a suitable screw 43 screwing into the end of the wedge 41. The printing form 44, preferably of etched zinc, or, if desired, a stereotyped form, is secured around the cylinder with its ends fastened to the sections 38 of the cylinder by screws 45, as shown in Fi 11, and after being thus secured is tightened by operating the screw 43, which will draw the wedge 41 longitudinally of the cylinder, separating the sections 38, their attached blocks 40 sliding in the grooves, and causing the surface of the printing plate or form to fit the cylinder tightly, the surface of the wedge 41 being flush with the outer surface of the cylinder making a smooth support for the form, which is necessary to insure good work.

It will be understood that larger or smaller print-ing forms may be employed by the use of different sized cylinder sections 38, and to permit this, it is, of course, necessary that the inking apparatus of each of the cylinders be adjustable, and this I accomplish in the manner now described.

Secured to the side pieces 1 of the main frame and preferably forming cap plates for the recesses in which the bearings of the type cylinders operate, are castings or frames 46 provided with ways on their inner sides in which slide castings or frames 47 carrying the inking apparatus and adjustable by means of screws 48 connected by beveled pinions 40 through a shaft 50 for causing the simultaneous vertical adjustment of the two frames, the ends of said shaft 50 being squared for the application of a wrench. In each of the said castings 47 are arranged ways for receiving bearing blocks 51, which are vertically adjustable by means of set screws 52, and each of these blocks is provided with an inwardly projecting boss 53, in which operates the shaft of the ink roller 54, one of said ink rollers being arranged on each side of the center of the type-cylinder to which it belongs. Mounted upon the sleeves 53 are radius arms 55, their upper ends being split and capable of being tightened around the sleeves, by screws 56, as shown in Figs. 7 and 8, while the lower ends of said arms are provided with cylindrical apertures in which are arranged sleeves or bushings 57, having eccentrically arranged apertures in which the ends of the inking rollers 58 are located, said sleeves being secured in any position of rotary adjustment by means of a securing plate 59 mounted on the arm and engaging the roughened outer edge, as shown in Fig. 9.

The inking rollers 58 are adapted to apply ink to the surface of the type form or cylinder and by means of the bushings 57, their surfaces may be adjusted relative to the surface of the rollers 54 to compensate for any shrinkage, and the radius arm 55 will insure their proper position relative to the rollers 54, as will be understood, even when type cylinders of different sizes are used.

Arranged between the bearings 51 are loose bearing-blocks 60 (see Figs. 5 and 14) in which an inking roller 61 has its bearings; said roller being provided with a gear 62 at one end meshing with the gear 42 on the type-cylinder and also with gears 63 arranged on one end of each of the rollers 54, as shown particularly in Fig. 1. The upper portions of the bearing blocks 60 are slotted for the accommodation of the ends of a roller 64 resting upon the surface of the rollers 54 and permitted a free longitudinal movement caused by a traveling distributing roller or vibrator 65 arranged upon a double threaded shaft 66; said roller 65 receivingink from a vibrating roller or duetor 67 supported upon arms 68 attached to a rock shaft 69, the latter being provided with an arm 70 having a slotted lower end, which latter is oscillated by a slide or cross-head 71 provided with a pin 72 operating in the slotted end of the arm; said cross-head being provided with pins 73 and moved back and forth by a cam 74 arranged on the end of the shaft 27, as shown in Figs. 5 and 6. The ductorroller 67 is adapted, by means of the devices just described, to be brought in contact with a roller 76, the latter operating in an ink-well 77 and moved intermittingly, through a rock arm 78 carrying a pawl and connected by a pitman 79 with a crank-pin 80 arranged on the cam 74, or otherwise connected to the shaft of the type-cylinder. The shaft 66, it will be understood, is prevented from longitudinal movement, but as motion is communicated to the roller 64 and by this to the roller 65, the latter will, as it rotates, carry both said last mentioned rollers back and forth distributing theink evenly upon the rollers 54, from which, by rollers 58 and 61, the ink is deposited upon the type-cylinders.

From the above it will be seen that the rotary adjustment of the various type-cylinders can be accomplished by the slotted connection between the gears 30 and the collars 29 on the type-cylinder-shafts, and thatthe longitudinal adjustment of the shafts and type-cylinders can be accomplished by means of the set nuts 34, so that the proper register on the paper or pasteboard web can be readily ac-' complished and the several colors or forms printed in proper position.

At the rear end of the machine, shown at the right in Figs. 1 and 4t, and at the left in Fig. 2, is provided a device for giving tension to the paper and preventing its wrinkling on the impression cylinder, and'also causing the printed portion to be presented properly to the severing devices, consisting, in the present instance, of a roller. 81 over which the paper passes anda shaft 82 having collars 83 thereon operating to press the paper or web tightly upon the roller 81, the shaft 82 being arranged in an eccentric bushing 84: supported in a supplemental frame 85, so that the pressure between the roller and the collars may be ad justed as desired; set screws 86 serving to bind said bushings after being adjusted. These two shafts are provided with intermeshing gears 87 driven from a gear 88 on a stud 89,-the last mentioned gear being driven from a gear 90 on a shaft 91, upon which is located a belt-pulley 92 driven by a belt 93 from a similar pulley 94: on the main driving shaft 9; the gears being so proportioned that the roller 81 and collars 83 (which latter constitute in effect a roller) are driven at a slightly greater surface speed than that of the main impression cylinder, so that the paper will be drawn taut all the time and a slight tension exerted on it. Just beyond these tension rollers and journaled in suitable bearings in a frame 95 are two rollers 96 and 97, the former being preferably of metal and solid and the latter having suitable cutting and scoring projections or ridges adapted to cut and score the web on proper lines to make folding-boxes or cartons, for instance, and beyond these are two rollers 98 and 99 connected for simultaneous rotation by gears 100. Theboxes 101 taohed to the roller 97, as shown in Fig. 1,

gears 108 transmitting motion to the rollers 98 and 99, and operating them at a greater surface speed than the movementof the web, from which, it will be seen, that when the rock shaft 103 is moved to bring the rollers 98 and 99into contact, the previously cut and scored web will be grasped and drawn outward, separating the box blanks, for instance, from the web and delivering said blanks at the end of the machine separately, so that they may be readily stacked and folded and the small pieces of pasteboard that may be adhering to them readily shaken off.

The scoring and separating devices are driven from the main gear wheel 7 through the medium of the double gears 109, 110, the latter meshing with a pinion 111 and the former connected adjustably to it by means of bolts 112, as shown in Fig. 1, and meshing with the main gear 7. Both the gears 109 and 110 are mounted upon an adjustable stud 113 operating in a slot in an arm 114 pivoted at 115 to the main frame and said arm is adapted to be secured by a bolt 116 operatingYthrongh its lower slotted end. This arrangement not only permits the removal of the cutting and scoring apparatus, but also permits its proper adjustment or alignment with regard to the web, and the variations of its speed relative to the main IOO impression cylinder, by the substitution of other gears for gears 109 and 110, the vertical adjustment of the latter being readily accomplished.

The operation of the whole machine will now be apparent. The forms being placed upon the type-cylinders in the manner described and by the various adjustments of the parts, caused to register properly, so as to print successively in several colors if desired upon the web or material, then as the web is printed and held under tension by the devices described, it is severed into blanks, which may consist of plain sheets instead of folding boxes if desired, and the rapidly revolving discharging rollers 98 and 99 serve to tear the blanks apart and deliver them at the end of the machine.

While I have shown only five type-cylinders, it is obvious that a greater or less number could be employed, or, if desired to use only two or more of these shown, the others could be thrown out of operation by the rotation of the shafts 50, raising the whole inking devices from the surface of the impression roller, and then, by means of the adjusting screws operating on the bearings of the type cylinders not used, lifting them.

This machine though particulary adapted for printing from more or less flexible etched zinc sheets is well adapted for using rigid stereotype plates if desired, attached to what I have termed type-cylinders, by means here described or other equivalent means.

I claim as my invention" 1. In a printing machine, the combination with the main frame having the radial recess, the main cylinder, and the type cylinder supported in bearings adjustable in said recess, of the removable cap piece extending across the recess in the main frame, the movable slides on the cap pieces, an inking device supported in the slides, and adjusting devices for moving the slides on the cap pieces connected forsimult'aneous operation, where by the inking device can be bodily adjusted on the cap pieces or removed bodily with them, substantially as described.
